Cloud Foundry Butler MCP server

This MCP server implementation facilitates read-and-write operations via one or more cf-butler instances installed on a target Cloud Foundry foundation. It serves as an intermediary that allows Claude to interact with your Cloud Foundry environments through the Model Context Protocol (MCP).

Installation

Prerequisites

Before installing the MCP server, ensure you have:

• One or more cf-butler instances deployed
• The following CLIs/SDKs installed:
  • git
  • gh (GitHub CLI)
  • Java
  • Maven
  • (Optional) SDKMAN - an easy way to install Java SDK and Maven
• Claude Desktop installed:
  • Windows and Mac
  • Linux

Building the Server

To build the MCP server, run the following commands:

cd /tmp
gh repo clone cf-toolsuite/cf-kaizen
cd cf-kaizen
mvn install

Configuration and Usage

Configuring Claude Desktop

After building the server, you need to configure Claude Desktop to use it:

1. Launch Claude Desktop
2. Open the File menu and select Settings
3. Click on the Developer tab in the left navigation pane
4. Click the Edit Config button
5. Open the claude_desktop_config.json file in your text editor
6. Add the following configuration within the "mcpServers": {} section:

"cf-kaizen-butler-client": {
  "command": "java",
  "args": [
    "-jar",
    "-Ddefault.url=https://cf-butler.apps.dhaka.cf-app.com",
    "/path/to/your/.m2/repository/org/cftoolsuite/cfapp/cf-kaizen-butler-server/0.0.1-SNAPSHOT/cf-kaizen-butler-server-0.0.1-SNAPSHOT.jar"
  ]
}

Important Configuration Notes

When adding the configuration:

• Replace /path/to/your/.m2 with the absolute path to your Maven repository:

  • On Linux/macOS: $HOME/.m2
  • On Windows: %USERPROFILE%\.m2

• If targeting multiple foundations, duplicate the entire JSON stanza for each foundation, separate them with commas, and update the default.url value for each instance.

Applying the Configuration

1. Save your configuration changes
2. Close and restart Claude Desktop for the changes to take effect
3. Verify that the additional tools appear in Claude Desktop before crafting prompts that use the MCP server

Once configured properly, Claude will be able to interact with your Cloud Foundry foundation(s) through the MCP server, allowing you to manage your environments directly through the Claude interface.

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
